Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum packaging, and in particular relates to a cavity type vacuum packaging mechanism. Background Art

[0002] As we all know, a vacuum packaging machine is a type of machine that vacuum-packs products to protect and extend the shelf life of products. Existing vacuum packaging machines are generally tube-type vacuum packaging, which requires tube insertion during use, resulting in wrinkles at the bag mouth and even leakage and deterioration of the product. The tube-type vacuum packaging is prone to sucking the product, resulting in packaging failure and affecting production efficiency. For this reason, a cavity-type vacuum packaging mechanism is urgently needed. Utility Model Content

[0003] In view of the technical defects existing in the background technology, the utility model proposes a cavity type vacuum packaging mechanism, which solves the above technical problems and meets the actual needs. The specific technical solution is as follows:

[0004] A cavity-type vacuum packaging mechanism comprises a vacuum bottom cavity and a vacuum cavity plate, wherein a gripper cylinder is provided on the front side of the vacuum cavity plate, a gripper is provided at the output end of the gripper cylinder, the other end of the gripper is arranged on the back side of the vacuum cavity plate, and the vacuum cavity plate is rotatably connected to the gripper, a fixed block matched with the gripper is provided on the back side of the vacuum cavity plate, a sealing pressure block is provided on the upper end of the fixed block, and a sealing cylinder matched with the sealing pressure block is provided on the front side of the vacuum cavity plate.

[0005] As an improvement of the above scheme, a guide shaft is provided at the lower end of the vacuum chamber plate, the other end of the guide shaft is provided with the vacuum bottom chamber, the inner side of the vacuum bottom chamber is provided with a sealing base adapted to the sealing block, and one end of the sealing base is provided with a fast heating wire.

[0006] As an improvement of the above solution, a transmission plate is provided at the other end of the guide shaft, a cavity cylinder is provided on one side of the transmission plate, a linear bearing is provided at the position of the vacuum bottom chamber corresponding to the guide shaft, and the guide shaft passes through the linear bearing.

[0007] As an improvement of the above solution, a blowing pipe is provided on the back side of the vacuum bottom chamber, and a vacuum pumping pipe is also provided on the back side of the vacuum bottom chamber.

[0008] As an improvement of the above solution, a sealing strip adapted to the vacuum chamber plate is provided at the frame of the vacuum bottom chamber.

[0009] The beneficial effect of the utility model is that the vacuum bottom cavity is divided into two identical working cavities, each working cavity is provided with a corresponding vacuum cavity plate, which can be used interchangeably during vacuuming, thereby realizing double-station processing and improving efficiency. The cavity-type vacuum packaging mechanism of the utility model can use the structure of the vacuum cavity to utilize negative pressure to discharge the internal air of the packaging bag, thereby realizing vacuum packaging. This process does not require intubation and will not cause wrinkles on the bag mouth. At the same time, the contactless vacuuming method will not suck the product, so the product qualification rate is high and the packaging efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0015] like Figures 1 to 3 As shown, a cavity-type vacuum packaging mechanism includes a vacuum bottom cavity 1 and a vacuum cavity plate 2, a gripper cylinder 3 is provided on the front of the vacuum cavity plate 2, a gripper 31 is provided at the output end of the gripper cylinder 3, the other end of the gripper 31 is arranged on the back of the vacuum cavity plate 2, and the vacuum cavity plate 2 is rotatably connected to the gripper 31, a fixed block 32 matched with the gripper 31 is provided on the back side of the vacuum cavity plate 2, a sealing pressure block 4 is provided on the upper end of the fixed block 32, and a sealing cylinder 41 matched with the sealing pressure block 4 is provided on the front of the vacuum cavity plate 2.

[0016] like Figure 1As shown, it should be noted that a guide shaft 5 is provided at the lower end of the vacuum chamber plate 2, the other end of the guide shaft 5 is provided with the vacuum bottom chamber 1, the inner side of the vacuum bottom chamber 1 is provided with a sealing base 6 adapted to the sealing block 4, and one end of the sealing base 6 is provided with a rapid heating wire 61.

[0017] like Figure 1 and Figure 3 As shown, it should be noted that a transmission plate 51 is provided at the other end of the guide shaft 5, a cavity cylinder 52 is provided on one side of the transmission plate 51, a linear bearing 53 is provided at the position of the vacuum bottom chamber 1 corresponding to the guide shaft 5, and the guide shaft 5 passes through the linear bearing 53.

[0018] like Figure 1 and Figure 3 As shown, it should be noted that a blowing pipe 11 is provided on the back side of the vacuum bottom chamber 1 , and a vacuum pumping pipe 12 is also provided on the back side of the vacuum bottom chamber 1 .

[0019] like Figure 1 and Figure 3 As shown, it should be noted that a sealing strip 13 adapted to the vacuum chamber plate 2 is provided at the frame of the vacuum bottom chamber 1 .

[0020] Working principle: before work, place the packaging bag 7 on the clamp 31, and use the clamp cylinder 3 to clamp the packaging bag 7 with the clamp 31 and the fixed block 32. At this time, drive the cavity cylinder 52 to move the vacuum cavity plate 2 toward the vacuum bottom cavity 1. The sealing strip 13 can form a sealed environment between the vacuum cavity plate 2 and the vacuum bottom cavity 1. As a preferred method, use a vacuum pump to extract the air in the vacuum bottom cavity 1 from the vacuum tube 12. The generated negative pressure will squeeze out the air in the packaging bag 7. At the same time, the clamp 31 clamps the bag mouth so that the product will not run out. After the vacuum is drawn, drive the sealing cylinder 41 so that the sealing block 4 presses the bag onto the fast heating wire 61. The fast heating wire 61 is energized, and the transformer outputs a large current, and the fast heating wire 61 heats up to seal the bag mouth. After the bag mouth is sealed, the fast heating wire 61 is de-energized, and then the sealing cylinder 41 retracts, and the blowing pipe 11 blows air, so that the cavity cylinder 52 opens the vacuum cavity plate 2 and the vacuum bottom cavity 1. After the cavity is opened, the clamping cylinder 3 opens the clamping cylinder 31, and the vacuum-packaged product falls into the finished product area, completing the packaging process. Preferably, the vacuum bottom cavity 1 is divided into two identical working cavities, each of which is provided with a corresponding vacuum cavity plate 2, which can be used interchangeably during vacuuming to achieve double-station processing and improve efficiency. The cavity-type vacuum packaging mechanism of the utility model can use the structure of the vacuum cavity to utilize negative pressure to discharge the internal air of the packaging bag 7, thereby achieving vacuum packaging. This process does not require intubation and will not cause wrinkles on the bag mouth. At the same time, the contactless vacuuming method will not suck the product, and the product qualification rate is high and the packaging efficiency is high.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
